Researchers have detected an extremely energetic cosmic ray from an unknown source in the universe. The detection of a cosmic ray with such high energy is "exceedingly rare" and the latest discovery, ...

The traditional astrophysical recipe for life as we know it is quite simple: Get a rocky, gas-shrouded world in a “habitable zone” orbit around a star so that it’s not too hot or too cold. Then just ...

In late November 2025, astronomers captured an unprecedented cosmic signature: the first X-ray emissions ever detected from an interstellar comet. As Comet 3I/ATLAS hurtled through our solar system at ...

Michigan State University astrophysicists are closing in on one of space science’s biggest mysteries: where the galaxy’s most energetic particles come from. Their studies uncovered a pulsar wind ...

Cosmic rays, high‐energy particles from extraterrestrial sources, continuously bombard the Earth, providing a natural probe of astrophysical processes. When these particles interact with the ...

Across the observable universe, galaxies advertise themselves in radio waves for familiar reasons-magnetic fields, cosmic rays, and, in those cases where it’s relevant, matter spiraling into a central ...
